Compression ulnar neuropathy was predicted by Guyon in 1961,following his anatomical studies of the ulnar tunnel. Nearly a half century later Ramsey Hunt first reported isolated ulnar motor paralysis in the hand, due to chronic occupational trauma. Many authors has tried to describe the etiology of the ulnar nerve compression syndrome at or around the wrist. That is most frequently caused by ganglion, occupational neuritis, thrombosis of the ulnar artery, thickening of volar ligament or different kinds of trauma (e.g. fractures of the carpal bones). Now we experienced a case of the ulnar nerve compression syndrome at distal forearm by an anomalous branch of the ulnar nerve by piercing the distal tendon of the flexor carpi ulnaris.

Lichen striatus is an uncommon unilateral inflammatory linear papular dermatosis of uncertain etiology. It most commonly affects the extremities and has a self-limiting course. Nail involvement in lichen striatus is a very rare reported finding and is a cause of a deformity of the nail plate. It tends to have a more prolonged course for cutaneous eruptions than disease limited only to the skin. Characteristic histopathological features are important to differentiate this condition from other linear lesions that may interfere with nail growth. Three cases of lichen striatus with onychodystrophy are presented herein.

There has been considerable controversies in the method of the treatment of dislocation of the acromioclavicular joint, especially in grade III injury. It is hard to give a direct firm repair having a short ruptured coracoclavicular ligament. Thats why there are lots of difficulties in the treatment. Therefore, in operative treatment, the authors make use of cotton tape on coracoid process and clavicle as a reconstructive technique, because we have thought a simple fixation of acromioclavicular joint adding to a firm fixation of clavicle and coracoid process is inevitable. From January 1991 to December 1995, twenty-nine cases of grade III acromio-clavicular dislocation were treated by the modified Phemister method with using the cotton tape. Twenty-four patients were followed for an average of fifteen months and the following results were obtained. 1. The clinical results were evaluated by Weitzman criteria after average fifteen months follow up. An excellent result was obtained in 19 cases (79.2%), a good result in 3 cases (12.5%) and a fair result in 2 cases (8.3%), consecutively. 2. Clinical result in patients over 60-year old were bad. 3. The comparison of the coracoclavicular interval ratio before surgery with that after surgery facilitated the evaluation of effectiveness of the coracoclavicular ligament reconstruction. 4. The operative technique is through temporary fixation using K-wires which endows horizontal stability, and it fixes clavicle and coracoid process using cotton tape which endows vertical stability.

There is still discussion concerning the methods for treating Tossy type 3 dislocations of the acromioclavicular joint. Since 1995, the authors have treated 10 patients of type 3 dislocations by arthroscope-assisted modified Weaver and Dunn operation with favorable results. The operation consisted of diagnostic shoulder arthroscopy, arthroscopic resection of acromial end of coracoacromial ligament with bone block, excision of distal end of clavicle, bone block transfer of coracoacromial ligament into the medullary canal of clavicle, and augmentation between coracoid process and resected distal end of clavicle with the Mersilene tape. The advantages of this arthroscope-assisted modified Weaver and Dunn operation are as follows: (1) Using the shoulder arthroscope, associated patholgy in the shoulder joint can be found and treated appropriately. (2) Arthroscopic resection of the acromial end of coracoacromial ligament can give the small incision and least damage to the deltoid muscle so that immediate post-operative range of motion exercise can be possible. (3) Bone block transfer of coracoacromial ligament and augmentation between coracoid process and resected clavicular end can prevent displacement of the resected clavicular end.

STUDY DESIGN: The lumbar segmental motions were analysed in asymptomatic volunteers. OBJECTIVES: To obtain normative data on flexibility and Graf's instability degree in sagittal plan of the normal lumbar spine. SUMMARY OF LITERATURE REVIEW: Although several clinical and radiological measurement tech niques are available, little is known about the normal range of lumbar spine motion. As a consequence, the diagnostic evaluation of radiographs are frequently based on subject opinions rather than object reality. MATERIALS AND METHODS: The authors have checked lumbar flexion-extension Yiews of 95asymptomatic volunteers who were divided into 5 groups by the age, and then their flexibility and Graf's instability degree were calculated by Graf's method with using Graf/Bar Mark II(digitalizing table) and personal computer program(RachisR). Evaluation of the sexual difference and comparison of the difference of each age group in spine level were done RESULTS: 1. There were significant differences in flexibility among age groups(p<0.05) and highest flexibility was observed in group 1 (age: 15-19yrs) and 15-19 segment 2. Flexibility was not different between male and female(p>0.05). 3. Graf's instability degree was not different among 5 age groups(p>0.05), and between male and female(p>0.05). 4. The mean Craf's instability degree was below 8o in L2-3, L3-4, and L4-5 segment, but above 8 in L5-S1 segment(male: 11.62+/-9.27 , female. 11.11+/-8.70). CONCLUSIONS: Although we observed small subjects, these results are the basic steps toward more objective and careful interpretation of flexibilty and Graf's instability degree.

PURPOSE: To evaluate protective mechanism of melatonin against radiation damage and its relationship with apoptosis in mouse jejunum. MATERIALS AND METHODS:' 168 mice were divided into 28 groups according to radiation dose and melatonin treatment. To analysis crypt survival, microcolony survival assay was done according to Withers an (l Elkind's method. To analysis apoptosis, TUNEL assay was done according to Labet-Moleur's method. RESULTS: Radiation protection effect of melatonin was demonstrated by crypt survival assay and its effect was stronger in high radiation dose area. Apoptosis index with 8 Gy irradiation was 18.4% in control group and 16.5% in melatonin treated group. After 18 Gy, apoptosis index was 17.2% in control group and 15.4% in melatonin treated group. Apoptosis index did not show statistically significant difference between melatonin treated group and control group. CONCLUSION: Melatonin shows clear protective effect in mouse jejunum against radiation damage but it.', protective effect seems not to be related with apoptosis protection effect.

This study was performed to investigate the relationship between CD44 expression and depth of, tumor invasion histopathologic differentiation, tumor size, lymph node metastasis, and proliferating capacity of tumor cells in the gastric carcinoma. In 20 cases of early gastric carcinoma (EGC) and 40 cases of advanced gastric carcinoma (AGC), the immunohistochemical staining for CD44v3, CD44v5, and PCNA gave the following results. 1) In all 60 cases, the positive rates for CD44v3 and CD44v5 were 18.3% and 71.7%, respectively. 2) CD44v5 was expressed in 45% of EGC and 85% of AGC. 3) Larger tumors exhibited higher positive rates for CD44v5. 4) There were 28 cases of lymph node metastases out of 43 cases of CD44v5- positive primary gastric carcinomas (65.1%), and there were 4 cases of lymph node metastases out of 17 CD44v5-negative cases (23.5%). 5) There was no relationship between CD44v5 expression and PCNA index. Because the tumors that exhibit deep invasion, and large in size and have lymph node metastses tend to have more frequent expression of CD44v5, CD44v5 may be one of the useful prognostic markers for gastric carcinoma.

Dyskeratosis congenita is a rare genodermatosis of ectodermal dysplasia, which is characterized by the diagnostic triad consisting of reticulated hyperpigmentation, dystrophic nails, and leukoplakia. There is a predisposition to malignancy, particularly at sites of leukoplakia. Bone marrow failure can occur in about a half of the cases. A 16-year-old boy was presented with asymptomatic reticulated pigmentation of the neck and nail dystrophy. The patient also had leukoplakia on the tongue, nasolacrimal duct obstruction and cataract. The histopathological findings taken from the reticulated lesion were consistent with poikiloderma atrophicans vasculare. These clinical and histopathological findings were typical features of dyskeratosis congenita.
